Sorry... The problem was in fopen(). The code had become something
like this (from memory):
if( append )
{
	f->_flag |= APPEND;
}

if( write )
{
	f->_flag = WRITE;
}
else
{
	f->_flag = READ;
}

So without any changes to fflush() it works fine now. 

The question is: did you find another real bug in fflush()?


Right,
